One, the expansion of the string The ES 6 strengthens support for Unicode. JavaScript allows a character to be represented in \uxxxxx, where xxxx represents the Unicode code point of the character. So there's a scope limit (\u0000 ~ \uffff).1. For ...The biggest advantage of this walker is that it supports code points larger than \uffff , which are not supported by traditional for loops.2. string.at (numberparam) and string.charat--it seems to be jus

Android uses ndk instead of yuv420 overlay to ensure smooth video display. Instead, it uses a platform to port a safer rgb565 display. Tested on Android 2.3.
However, the MTK andriod platform (a301) encountered a glteximage2d gl_error 0x501 error (the source image is 176*144 ). After repeated tests, this MTK andriod version supports OpenGL ES, but it has a strange limit on the resolution of the source image. When the source dimension width and height
Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently.
> OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we need to implement a complex interface, especially for game development, and draw a large number of images in the main thread, it will

OpenGL ES coloring language defines a set of built-in convenience functions for scalar and vector operations. Some of the built-in functions can be used in multiple types of shaders, some for fixed hardware, so this part can only be used on a particular shader.The built-in functions can basically be divided into three categories:(1) They provide the necessary hardware functionality, such as material mapping, in a few easy ways. These functions cannot
The android framework provides a large number of interactive and powerful graphic user interfaces. But if you want more painting on the screen or 3D display, you need to use different tools. OpenGL ES api provides a large number of tools to display high-end animated images.
The following describes how to use OpenGL Es to develop applications. Including creation, painting objects, Moving Elements, and contr
Since the original book of the OpenGL ES 2.0 Programming Guide does not provide the sample code for the 12th chapter, the code in the book only mentions the key steps, and most of the Web is an example of the Android/ios version, most of which are based on OpenGL or OpenGL ES 3.0, in order to deepen understanding, so that their own implementation of a C language version, hoping to help the same like OpenGL
We've explained how to build a Hello World development environment, so we'll draw a simple triangle out of this one. First of all, I would like to introduce the OpenGL ES rendering process, before 2.0, ES rendering using fixed pipeline, what is fixed pipeline, is a set of fixed template flow, Local coordinate transformation, world coordinate transformation, observation coordinate transformation-- > Lighting

Simon iPhone-OpenGL ES tutorial-04 OpenGL ES 04-color and texture
As my last tutorial said, I'm tired of drawing white objects on the screen, so that we can add some colors, just like the project automatically generated by the apple module. Next I will introduce you to pay attention to these concepts, because these concepts will work backwards (very fast) when we start texture rendering)

OpenGL ES Tutorial for Android-Part III-Transformations
January 1st, 2010 by Per-Erik Bergman-Android,Embedded
Last tutorial was about building your polygons. this tutorial is all about transformations, how to move the polygons around. I will continue this tutorial from where the previous ended so you can use that source code or make a copy of it.
The previous tutorial details how to create a polygon. This tutorial describes how to move and transform
OpenGL ES 11-moving in 3D
(TRANSLATOR: That. In fact, I jumped to another chapter, section 12, and learned how to judge an object in the 2D world, I think most of our game developers have already used huge peanut code, and it is easier to develop games in the 2D world. This chapter is of little use to us. So I am also lazy .)
Bird flu, busy, Mother's Day, and other things mean that I am not here for a while. So now is the time to do things.

OpenGL ES Tutorial for Android-Part VI-Textures
December 30th, 2010Per-Erik Bergman-android,Embedded,Java
Last Tutorial we worked a bit more on meshes and we have also talked about adding colors to our mesh. the most common way of adding colors to your mesh is to add a texture. there is a couple of different steps involved with adding a texture to the mesh IWill try to go through them all and explain the basics about them.
In the previous tutorial, we
The digital signal actually transmits data streams. Generally, the data streams include the following three types: ES is the original code stream, and contains the continuous code streams of video, audio, or data. Ts is a transmission stream consisting of 188 bytes in a fixed length. It contains one or more programs with independent time bases and is suitable for environments with many error codes.
We all know that the TS package starts with 0x47 and
My 1st OpenGL ES program for wince5 HTC touchhd

After lunch, I had nothing to worry about. I looked at my cell phone (HTC touchhd) and suddenly wanted to compile an OpenGL program for fun. Download the OpenGL ES development kit from csdn.
After decompression, several files are found in the bin/ARM/release directory:
Libgles_cm.dll
Libgles_cm.lib
Libgles_cm.exp
And so on. I'm going to copy libgles

It took four days to transfer an FPS game engine fly3d to OpenGL ES. As we all know, ES is intended for mobile devices, so for efficiency, it performs a lot of screening and subtraction on OpenGL, throwing away all inefficient functions such as (glbegin) and throwing away some of the drawn types such as gl_polygon,
Here we will share with you the alternative method of using gldrawarray to draw polygon.And
I am not very busy recently. I plan to start learning OpenGL this week. There are already many books and materials on OpenGL on the Internet. The reason for writing is to develop a good learning habit and give a summary of your learning process.
Basic Concepts
OpenGL defines a cross-programming language and cross-platform programming interface specification. It is a high performance 3D graphics standard. OpenGL is a professional graphical program interface and is a powerful underlying graphics l
